Prepositions and parsing

[clawrenc#cup,hp.com]

What with the recent discussion of parsers and methods of parsing
commands, and old entry from my to-do list popped up:

  Support for prepositions such as "under", "on top of", "behind" etc.

Anyone got any ideas for supporting/parsing a command like:

  hide under the desk

or

  put the rock under the rug behind the pillar
